In the "Magic Baby" Episode, Juniors father tricks him into having self confidence and thinking that the baby is magic. Just by touching the baby, Junior knows all sorts of facts that his parents didn't know he knew. One is where his fathers asks him "What is pi?" and Jr. says "A delicious dessert." Then Jr. touches the baby and says "Pi is a number equivalent to approximately to 3.41752 or 22/7." Actually Pi is equal to 3.14.
